Thorgan Hazard wants his long-term club future sorted before the end of the season as Borussia Monchengladbach continue talks with Chelsea over a permanent transfer.

The 21-year-old Belgian, younger brother to current Blues star Eden, has impressed management while on loan at the Bundesliga club this season, prompting the club to initially look into extending his deal back in December 2014.

While Jose Mourinho has been impressed with the player, Chelsea's current options, none more so than the older of the Hazard brothers, are likely to prevent him from breaking into the first team having still not made his debut for the club two-and-a-half years on from his arrival.

Speaking in February, Gladbach's sporting director Max Eberl spoke confidently of ongoing talks with the Premier League side, admitting 'Chelsea can see the transfer happening'.

And Hazard is hopeful of a resolution being met soon, telling Kicker: "I believe that there will be a decision before the end of the season – the sooner the better," ESPN report.

Speaking to Gladbach's official website, sporting Eberl also confirmed Hazard would like to stay at the German side, one of three key factors the club have identified in getting the deal confirmed.

"The fact of the matter is that Thorgan would like to stay here, Chelsea can see a transfer happening and we want to sign him," Eberl said.

"All three are very positive signs, so we will try to come to an agreement and hopefully get a contract agreed."

Hazard, who joined his brother at Stamford Bridge from Lens in 2012, enjoyed an excellent loan spell back in his homeland with Zulte Waregem before linking up with Gladbach in the summer of 2014.
